Manufacturing rough plans and detailed schedules must establish a compromise between antagonistic optimization criteria: meet as much as possible of the established and expected customer demand; deliver customer demands on time; reduce production costs (processing costs, resource usage costs, setup costs, cleaning costs); keep little value in inventories without risking starvation, and so on. U...

Using second-generation biomass and biofuel deal with environmental pollution and CO2 emissions. Therefore, this paper design an integrated multi-period bi-objective biofuel supply chain network using support vector machine (SVM) and economic analysis to reduce the cost of generating biofuels and CO2 emissions. The economic analysis consists of three scenarios for supplyin...

Nowadays, with the increasing pressure of the competitive business environment and demand for diverse products, manufacturers are force to seek for solutions that reduce production costs and rise product quality. Cellular manufacturing system (CMS), as a means to this end, has been a point of attraction to both researchers and practitioners. Limitations of cell formation problem (CFP), as one o...

Manure in an inevitable byproduct of the production of meat and milk destined for human consumption. Excessive excretion of manure and manure nutrients represent inefficiencies which increase feed costs, increase the environmental impact of dairy farming, and increase the costs associated with moving and storing manure. Profitability can be enhanced when good feeding and management practices ar...
